Question

I managed to cobble together a join statement to give me a single table that displays my entire database. Now I need to narrow the results down to just the last 30 days, but I cannot for the life of me figure out how to work this restriction into the query.

Right now I have:

select customers.name, customers.email, orderinfo.orderno, orderinfo.orderdate, status.state, orderinfo.lastupdate 
from customers 
where orderinfo.orderdate = curdate() 
inner join orderinfo on customers.id=orderinfo.fk_id 
inner join status on orderinfo.fk_code=status.code 
order by customers.name;

…in an attempt to just narrow it down to showing me all the records for today, but even that is not working. I see there are a variety of ways of doing the 30-day thing but the part I’m having the most trouble with is just getting the WHERE clause to work at all in this query.

Thanks for any advice!

Answer 1

The WHERE clause needs to go before the ORDER BYand after all joins.

select customers.name, customers.email, orderinfo.orderno, orderinfo.orderdate, status.state, orderinfo.lastupdate 
from customers 
inner join orderinfo on customers.id=orderinfo.fk_id 
inner join status on orderinfo.fk_code=status.code 
where orderinfo.orderdate = curdate() 
order by customers.name;
